Description
Изобретение относитс к испытани м и исследовани м электрических машин, в частности к способам экспериментального определени параметров синхронной машины. Известен способ определени индуктивного сопротивлени рассе ни обмотки статора, согласно которому ротор машины замен ют на испытательный , содержащий измерительную обмотку , а указанное сопротивление вычисл ют по результатам опыта питани ста тора переменньм напр жением 1 . Недостатками этого способа влЛютс сложность, а также низка точность из-за изменени распределени магнитного пол машины при замене ее роторов на испытательньй. Наиболее близкий к изобретению по технической сущности и достигаемому результату способ измерени индуктивности рассе ни обмотки статора синхронной машины с обмоткой возбуждени путем подключени обмотки статора к сети переменного тока, измерени ЭДС разомкнутой овмотки возбуждени при неподвижном роторе и мгновенных значений токов и напр жений фаз при одном из экстремальных значений ЭДС, например при нулевом значении ЭДС обмотки возбуждени Г. Однако известньА способ предполагает разворот ротора до совме1цени его оси с осью контролируемс фазы, что часто затруднено в пpo lшшeнныx услови х, особенно дл машин больной мощности. В указанных услови х трудно достичь необходимой точности в установке ротора в нужном положении, что прнводат к погрешност м в определении индуктивности рассе ни . Цель нзобретенн - упрощение н повышеше точности определени индуктивности рассе ни . Дл реализации поставленной цели дополнительно измер ют мгновенные значени фазных токов и напр жений при другом экстремальном The invention relates to tests and studies of electric machines, in particular, to methods of experimentally determining the parameters of a synchronous machine. There is a known method for determining the inductive resistance of the stator winding, according to which the rotor of the machine is replaced by a test one containing the measuring winding, and the resistance is calculated from the results of a stator powering test with alternating voltage 1. The disadvantages of this method are the difficulty as well as the low accuracy due to the change in the distribution of the magnetic field of the machine when replacing its rotors with the test ones. The closest to the invention of the technical essence and the achieved result is a method of measuring the inductance of the dissipation of the stator winding of a synchronous machine with the excitation winding by connecting the stator winding to an AC network, measuring the EMF of the open excitation winding with a stationary rotor and instantaneous values of currents and phase voltages at one of the extreme values of EMF, for example, at zero value of EMF of excitation winding G. However, limestone method implies a turn of the rotor to combine its axis with the axis troliruems phase that is often difficult to ppo lshshennyx conditions, particularly for vehicles power patient. Under these conditions, it is difficult to achieve the required accuracy in installing the rotor in the desired position, which leads to errors in determining the scattering inductance. The purpose of the inventive is to simplify and improve the accuracy of determining the inductance of the scattering. To accomplish this goal, the instantaneous values of phase currents and voltages are additionally measured at another extreme
